Basic Example

This example demonstrates a complete Windmill setup with Watermill, Redis Streams, and a Poison Queue.

Prerequisites

• Redis running on localhost:6379
• Go 1.21+

Setup

1. Set Authentication Credentials

Windmill requires Basic Auth. Set these environment variables before running:

export WINDMILL_USERNAME=admin
export WINDMILL_PASSWORD=secret

2. Start Redis

docker run -d --name redis -p 6379:6379 redis:alpine

3. Run the Example

go run main.go

4. Open the Dashboard

Visit http://localhost:3000 - your browser will prompt for the credentials you set above.

What This Example Does

1. Publishes messages to random topics (orders.created, payments.processed, notifications.sent)
2. Consumes messages with handlers that randomly fail ~30% of the time
3. Routes failed messages to the Dead Letter Queue (DLQ)
4. Serves the Windmill dashboard for monitoring and managing messages

Features Demonstrated

• Stream monitoring with message counts and memory usage
• DLQ management (view, requeue, delete failed messages)
• Real-time activity tracking
